Embodiment Construction

[0044] Identical or similar components in the figures are provided with the same reference numerals. The figures show examples only and are not to be construed as limiting.

[0045] figure 1 A perspective view of a filter system 100 is shown having a tangential inlet 102, a central outlet 104 and a dirt outlet 106 at the bottom, according to an embodiment of the invention. A circular filter design is shown comprising a housing 108 closed with a cover 110 on one front 120 . In the air filter system, the dust-laden air flows through the inlet 102, which is arranged tangential to the housing wall and tangential to the air filter element mounted on the inner side, also tangential to receive the untreated flow In the flow chamber, the flow chamber surrounds the annular air filter element to put the air in the housing 108 into rotational motion. The direct entry of air through the inlet 102 into the folds of the air filter element present in the inlet area is prevented by a baffl...

Abstract

The invention relates to a filter system (100) comprising a shell (108) with a longitudinal axis (L), a cover (110) for closing the shell (108) at the front surface (120) thereof, an inlet (102) used for supplying a to-be-filtered medium and arranged on the shell (108), an outlet (104) used for discharging the filtered medium and arranged on the shell (108), and a replacable fitler element (10) arranged in the shell (108). The fitler element (10) is composed of a fitler body (12), a first open end plate (16) arranged on the front surface (15) thereof, and a second end plate (18) arranged on an opposite front surface (17). A support tube (14) attached onto the shell is arranged concentrically on the iner side of the fitler element (10) around the longitudinal axis (L). The the fitler element (10) provided with the second end plate (18) supported by the support tube (14) abuts against an inner cover contour (114) of the cover. The invention also relates to the fitler element (10) and an auxiliary elemnt (28) applied to the filter system.

Description

technical field [0001] The invention relates to an air filter system, in particular for use as an air filter for an internal combustion engine, and to a filter element for installation in such a filter system. Background technique [0002] A filter system with a filter element for an internal combustion engine is known from WO 2009 / 047196 A1. The filter system is used in particular to filter the intake air of an internal combustion engine and consists of a housing and a cover for holding the filter element, wherein the filter element is constructed by means of two toroidal structures and a sealing groove between them. A design of the seal which ensures a sealing effect on the one hand and an axial support of the filter element in the housing on the other hand. Especially when using synthetic materials for seals on elements subject to vibrations, this requires a design that will also function reliably during extreme temperature fluctuations. [0003] WO 2009 / 047196 A1 also ...
